Best AI visibility tools: 9 criteria for comparing them fairly

What makes an AI visibility tool worth using?

It has to answer one question reliably: for the questions your customers ask, do assistants name your brand, where, and next to whom. Everything else is packaging. A tool that cannot show you the answers behind its numbers is hard to defend to a client or a boss.

This guide comes from a vendor, haylow.ai, so treat it as a checklist rather than a ranking. Use it on every tool, including ours.

Which engines does it cover?

Check that it covers the assistants your customers use. For most B2B and consumer brands that means ChatGPT, Gemini, Claude and Perplexity at least, and Grok or Google AI features if your audience uses them. Engines behave differently, so a single-engine view can mislead.

Ask whether coverage is the same on every plan, and whether new engines are added without a price change.

Where does the data come from?

Ask whether the tool uses official APIs, scraped consumer interfaces or a mix. Official APIs are stable and permitted but may differ slightly from the consumer app. Scraping can mirror what users see but can break and may breach a provider's terms.

Neither is automatically better. What matters is that the vendor states it plainly and that the numbers are consistent from week to week.

Can you control and inspect the runs?

Look for control over when checks run and what they cost, and for stored answers you can read in full. Scheduled runs you cannot pause can burn credits on questions you no longer care about. Stored answers let you verify any score.

• Run control

  Can you start a run yourself, set limits and see the cost before it runs?

• Stored answers

  Is the full answer text kept for every question and engine?

• Repeat runs

  Does it repeat each question so you see a rate, not one lucky result?

How is pricing structured?

Convert every plan to a cost per tracked question per month and compare. Check what happens when you add questions, engines or brands, whether prices are in your currency, and whether tax is included. A cheap plan with tight caps can cost more than it looks.

Also look at overage rules. A tool that stops at a limit is easier to budget than one that bills you automatically.

What do reporting, access and exports look like?

If you report to clients or a leadership team, check for shareable reports, role-based access and an audit trail. Check that you can export prompts and results, because you will want your history if you ever switch tools.

Run a two-week trial with the same ten questions in two tools. Compare the answers, the positions and how easy it is to explain each number.
